Schema comparison

You can compare two database objects in the selected database platforms under specified scope. Here’s how it works:

  1. Create a new project or open an existing one.

  2. Define the operation scope by choosing the desired nodes on metadata trees.

  3. Click the Compare button in the Schema Operations panel.

  4. Click the Matching button to proceed to the matching page. Here you can adjust objects matching if needed. Otherwise, click the Tree branches button at the bottom left-hand corner of the central window if you need to get back to the node selection operation.

  5. Click the Options button at the bottom right-hand corner of the central window. You will get to the Schema comparison options page.

  6. After picking up the desired options, click Run button at the bottom right-hand corner of the central window to get the result. Otherwise, click the Matching button at the bottom left-hand corner of the central window if you need to get back to the matching page.
